Quality AspectsThe more sequences a production process

involves, the higher the number of factors on

which the quality of the finished product depends.

The properties and the homogeneity of the

molding sand greatly influence the quality of

the molds, the cores, and, of course, the finished

castings. Hence, inspection and control of the

molding sand properties within set tolerance

limits are indispensable.

• In many cases, constant supervision of

all production steps and the statistical

documentation of the results — as part of the

quality assurance system — are compulsory.

• Continual in-process sand control will not

only help to minimize fluctuations in molding

sand consistency, but will also help to

optimizes and recipes and to make them

infinitely reproducible.

Therefore, molding sand testing is not merely

an option, but an absolute necessity.

In today’s highly competitive market, quality and price are imperative for the success of a product. No matter

how complex the manufacturing process — what really counts is whether the product is good or scrap, and

how it compares with competitive products in terms of price and quality.

Economic AspectsIn addition to quality requirements, there is a

demanding need for cost-efficient production

and more economical use of resources and

materials. Molding sand testing has become a

must, because it facilitates the selection of more

suitable, therefore, more economical molding

sand components.

Molding sand testing will, among other things,

enable foundries to determine the exact amount of

binder and other sand additives needed to produce

the mold best suited to meet the quality standards

specified for the casting.

Molding sand testing can be instrumental in

developing sand mixtures that are better adapted

to a particular foundry operation and will help

prevent sand-related rejects.

Moreover, the proper choice of a suitable sand

mixture that will help foundries achieve the required

mold configuration, maximum dimensional accuracy

and high-quality surface finish, will in turn, lead to a

reduction in shot blasting and finishing costs.

PROPERTIES OF THE BASE MATERIALS

Washing

PKA Continuous Clay WasherThe washer serves to remove all fines of size < 0,02 mm from two samples at the same time.

The Clay Washer works on the principle ofelutriation, i.e. by holding the sample in anupstream water current of a velocity equalling the sedimentation speed of the particles size < 0,02 mm.

PWB AgitatorTo determine the fines content, particles of size < 0,02 mm must be separated from the grains and brought into suspension. This requires intensive and thorough agitation of the prepared sample.

PNZ-D Digital Wet Tensile Strength Testing ApparatusBy heating the top face of a cylindrical standard test specimen, a temperature gradient is produced. This creates a zone of overwet sand(the so-called condensation zone) with reducedstrength, a few millimeters below the surface.Exposed to a tensile force, the test specimenruptures in this zone. The wet tensile strength inN/cm2 is read from the maximum indicatorpointer (up to 0.6 N/cm2) and is a direct valuefor the evaluation of bentonite and moldingsands.

PGD-E Gas Pressure Measuring DeviceThis device serves to measure the gas pressureand, indirectly, the gas volume (the sum of allgasses). It also measures the rate of gasformation. The temperature of the PGD-E can be set electronically and reaches the maximumtemperature of 1000° C within 12 minutes, whichallows to carry out the test with a test sample of0,5 – 2 g. With a special software (included) the pressure diagram can be displayed on acomputer.

230 V, 50 Hz, 2000 WMax. temperature up to 1000° CPressure: max. 500 mbar

*Laptop not included.

PWG Moisture AnalyzerThis device serves as a dryer. It also evaluates and automatically records the water contents.Max. weighing capacity: 35 g (or 150 g)Weighing accuracy: 1 mgRepeatability, average (%) for initial sample weight:
